Metric and SAE

[TxDoc]

I had heard this, but not encountered it. Now I am seeing it. How long ago did they do this? Not a big deal, I have both, but don't know when to expect SAEand when to expect metric.

Thanks

My 88 GMC had both metric and SAE and my 78 Chevy had all SAE as I recall.

It's annoying isn't it.  I wish they'd stick w/ one or the other. Preferably metric, but it gets annoying having to sift through two different socket sets.

 

Although I have noticed over the years it has become more and more metric.

It's been a long while, so I don't remember anything on the 73 Cadillac

 

There was both on my 77 TransAM, I'd say less than 5% metric.

 

On my 83 Caprice and 84 TransAm, it seemed to be an annoying 40% metric.

 

On my 88 TransAM GTA 95%+ on body, annoying 50% on engine.

Almost everything on my 1997 Camaro was metric.

The whole metric thing pissed me off...I had a 77 Chev all SAE...then to the 1990 Cherolet Silverado 1/2 ton with metric on her all over....followed by the 99 and 02 which have equal if not more metric......ahh GM what were you thinking????

my dads 92 S-10 has both.  We changed out his shocks last friday and had to use std and metric

 

Luckily i have a nice craftsman mechanics set with both std and metric

Yeah I have noticed that, but I have gotten by using all metric tools, which is good cause that is all I have.  I wish they would just stick with the metric, though it seems to me that everything on my truck so far is metric. :thumb:

It all depends on who manufactured the part. GM has so many different vendos for the same part, you could get one that has SAE, and the same part from another vendor that is Metric (ISO). It sucks.

Ever since we started subbing out work and production to Canada and Mexico and the USA blew off the ISA standard in

the 70's. It really is a simple method of 10's and 100's.

That's NAFTA, your soaking in it.

 

Have a great one!
